Hi everyone! I have been researching extraction Teks, and found this article:
Rossi, G. N., Crevelin, E. J., Silveira, G., Queiroz, M. E. C., Yonamine, M., Hallak, J. E. C., & Santos, R. G. D. (2019). Internet method for the extraction of N,N-dimethyltryptamine from Mimosa hostilis roots: Does it really extract dimethyltryptamine? Journal of psychedelic studies, 3(1), 1–6. https://doi.org/10.1556/2054.2019.009

The researchers used Lazy Man Tek with different NPS, and found that n-butanol gives like 20 times more yield than hexane (so naphtha basically). I plan on doing an extraction with n-butanol, but gettin the spice out of the NPS is a bit more challenging. Freezing does not seem to work well. A user named Ruffles did a butanol extration a few years ago (https://www.dmt-nexus.me/forum/default.aspx?g=posts&t=97196), and used FASA to extract the crystals. I want freebase, not fumarate, and evaporating the solvent seems easier than using FASA and then converting it.

The problem is that butanol is less volatile than naphtha, so in order to get the evaporation done before the heat death of the universe, some heating would be really useful.

So here is my question: Would prolonged heating at around 50-70 °C (120 - 160 °F) degrade the DMT in any way? Or would I lose yield due to some product evaporating with the solvent?

I plan on doing this extraction within a few weeks, so i'll post results when I'm done. I might do an identical extraction with regular naphthane as well later, to see if butanol gives superior yield.

N.B. If anyone reading this wants to try this, keep in mind that butanol can easily form an emulsion with water, so don't shake! Adding non-iodized table salt can also help.

Edit:
After thinking about it for a few more days, I don't think using butanol is more effective than naphtha. The paper Mentioned extracted about 0.55% product from the MHRB using butanol, which is a very standard yield. It seems that the reason they could not extract much with hexane is the fact that they only used a single pull, so not all the product was transferred to the hexane.

It seems that butanol is a much more effective solvent for DMT than hexane, but this should not matter much as long as you do enough pulls, as in the end, nearly all DMT will be extracted from your aqueous solution anyway.

Seeing that working with butanol is a headache, and that butanol is much more expensive than naphtha (20€/L vs 1€/L, where I live), there seems to be no reason for using butanol, as it is most likely not any more effective than naphtha.

So I'll leave it at that, but if anyone else wants to try using butanol, it would be interesting to check if there is indeed little increase in yield or not.

An article on pubchem states boiling point of DMT is 60 - 80 degrees C. Melting point 46 degrees C. https://pubchem.ncbi.nlm...ne#section=Boiling-Point

Wikipedia says boiling point DMT 160 degrees C. https://en.m.wikipedia.o...i/N,N-Dimethyltryptamine

The lower boiling points are under varying degrees of hard vacuum. Always check the pressure data for any given boiling point. The 60 - 80°C range is both vague and well-known.

Vliselnur - just collect the DMT as fumarate and convert back to freebase afterwards. It will be so much quicker, easier and more energy-efficient that way.
